Patent CA-2376923-A1 (CA)
Title: Prevention of type 1 diabetes and other non-polio enterovirus diseases
Inventor: HYOTY HEIKKI
IPC: A61P31/12
Filed: 2000-03-17
Abstract: Live virus vaccines comprise attenuated viruses, while other vaccines comprise killed viruses or parts thereof. It has now been found that the immune response induced by oral poliovirus vaccine (OPV), which is a live vaccine, is cross-reactive with non-polio enteroviruses. OPV is therefore useful in the prevention of non-polio enterovirus diseases, especially Type 1 diabetes mellitus (IDDM). OPV is also useful in combination with killed/subunit non-polio enterovirus vaccines, whereby it prevents harmful side-effects of the killed/subunit vaccine by shifting the immune response from a harmful Th2-type response to a Th1 type response.

Patent CA-2387700-A1 (CA)
Title: Scanned display with pinch, timing, and distortion correction
Inventor: ESLAM BASHIR Z
IPC: G02B26/10
Filed: 1999-10-29
Abstract: A display apparatus includes an image source that scans about two axes. To offset motion about a first of the axes during sweeps about the second axis, the apparatus includes a structure to produce offsetting motion about the first axis at a scanning rate equal to the twice-scanning rate about the second axis. The offsetting scan can be a ramp or other motion. In one embodiment, the offsetting motion is a resonant sinusoid. The offsetting motion may be produced by an auxiliary scanner such as a mechanical scanner, a piezoelectric scanner, a MEMs scanner or other scanner. Because the offsetting motion is very small, the auxiliary scanner can function with a very small scan angle.

Inventor: LANE JOSEPH A
IPC: B65D85/72
Filed: 1996-10-16
Abstract: A universal elastomeric compound whose improved features display excellent permeability while simultaneously having above average chlorine compatibility. This improved elastomeric compound comprises a measured quantity of a terpolymer of ethylene-propylene-non-conjugated diene copolymer (i.e. EPDM, e.g. ROYALENE*3180), chlorinated Isobutylene (e.g. Chlorobutyl* 1066), furnace or carbon black (e.g., N-550*Black), paraffinic oil (e.g., Sunpar*150 oil), organofunctional magnesium silicate (e.g., Mistron*      CB), magnesium oxide (e.g., Maglite* D Bar), zinc oxide, stearic acid, tetramethylthiuram disulfide (e. g., TUEX*, zinc thiophosphate (e. g., ROYALAC*136), and treated sulfur (e.g., Spider*Sulfur). Adding a specified quantity of said ROYALAC 136, TUEX, and Spider Sulfur to the EPDM/butyl compound imparts low taste and odor to water. Additionally, adding a specified quantity of said Mistron CB to ROYALENE 3180 and Chlorobutyl 1066, provides for an elastomeric compound having excellent resistance to chloramines.      Because the herein prescribed combination of EPDM, butyl and other disclosed compositions exhibits low gas permeability, a high degree of chlorine compatibility, imparts low taste and odor to water, exhibits good flex characteristics, in addition to yielding extractants below the requirements of ANSI/NSF Standard 61 Health Effects Standard, the compound can be effectively used as an elastomeric barrier (e.g., a *Trademark diaphragm structure) in water storage and treatment systems, valves, pumps or the like.

IPC: A61M25/01
Filed: 2001-02-27
Abstract: An introducer apparatus (10) comprising a pair of co-extending splittable introducer sheaths (11), (12) is disclosed.  The unique properties (pushability, torqueability, length, shape, etc.) of the individual introducer sheaths yields an introducer appara-tus with the additional navigational flexibility to reach a remote target that whose access would be more difficult or impossible with a single introducer sheath. One embodiment include a coaxial pair of introducer sheaths made of molecularly oriented (non-isotropic) polytetrafluoroethylene PTFE which are used for placement of a pacemaker or defibrillator lead into the coronary sinus. In this embodiment, the first introducer sheath (11) is introduced over a wire guide into ostium of the coronary sinus, which represents the first target site. The outer introducer sheath includes preformed bends (20) to facilitate passage through the vasculature. A second introducer sheath (12), which includes a curved distal portion (17), is introduced through the first introducer where it extends from the distal end of the outer introducer sheath to access the second, ultimate targer site, such as a coronary artery branching from the coronary sinus. After the pacemaker lead has been placed, both sheaths are split and removed from the patient.
